Guide to desktop notifications

Slack notifications keep you informed about things that need your attention. Learn how notifications work on your desktop and how to customize them to suit your needs.

How notifications work

When you first join a workspace, Slack will notify you of messages for you. By default, here’s when you’ll receive notifications:

These settings apply to both desktop and mobile notifications until you make changes. If you’re having issues, skip ahead to Troubleshooting notifications.

Note: If your workspace has 50 members or less, you'll receive notifications for every new message by default.


Configure your notifications

The default desktop notifications are automatically enabled as soon as you join a workspace. Use the steps below to customize your preferences.


Notification triggers

By default, only @mentions, direct messages, and keywords will trigger desktop notifications. You can change this preference to include all messages sent to channels you're a member of, or nothing at all:

  1. From your desktop, click your profile picture in the top right.
  2. Select Preferences from the menu to open your notification preferences.
  3. Under Notify me about, choose your notification triggers.

All members automatically receive notifications when someone replies to a thread they're following. Uncheck the box to stop getting those notifications.

Note: By default, Slack for Windows notifications are set to deliver via Slack for Windows 7, and via the Windows Action Center for Windows 10.

Notification sound and appearance

  1. From your desktop, click your profile picture in the top right.
  2. Select Preferences from the menu to open your notification preferences.
  3. Under Sound & appearance, choose how your notifications will look, sound, and behave.

Tip: To pause your notifications, click your profile picture, then hover over Pause notifications to select a period of time.


Badge notifications on the Slack icon

When you have an unread notification, you’ll see a badge in the top right corner of the Slack desktop app icon.

Default badge notifications

By default, any unread activity will display a red badge on the Slack icon.

  • A dot means you have unread activity in one of your Slack workspaces.
  • 3 A number means someone sent you a direct message, mentioned you, notified a channel you're in, or used one of your keywords.

If you'd like, you can remove badges from the Slack app icon by following the steps below.


Set your badge notification preference

  1. From your desktop, click your profile picture in the top right.
  2. Select Preferences from the menu to open your notification preferences.
  3. Under Sound & appearance, check or uncheck Show a badge on Slack's icon to indicate new activity.

Tip: If you're a member of multiple workspaces, you can pick and choose the ones you'd like to see badge notifications for.

On Windows, you'll see badge notifications in two places: in your taskbar and in your notifications area.

Taskbar

In your taskbar, a red badge means someone sent you a direct message, mentioned you, or used one of your keywords. If your taskbar is set to small taskbar buttons, badges on the Slack icon will not be visible.

By default, the Slack icon will flash once when receiving a notification if your computer has been idle for 10 seconds. You can choose to have the icon flash when you're active: 

  1. From your desktop, click your profile picture in the top right.
  2. Select Preferences from the menu to open your notification preferences.
  3. Scroll down to Flash window when a notification is received and select Always.

Tip: Selecting the preference Always will also keep the Slack icon in the taskbar when the app window is closed. 

Notifications area

When Slack is running, you’ll see a Slack icon in your notifications area.

A red badge means a teammate sent you a direct message, mentioned you, or used one of your keywords.

By default, your app is set to keep running in the notifications area even when the window is closed. Choosing not to leave the app running will remove the Slack icon and badges from your notifications area. Here's how to prevent the app from running in the notifications area when the window is closed:

  1. From your desktop, profile picture in the top right.
  2. Select Preferences from the menu.
  3. Click Advanced.
  4. Below Other Options, uncheck the box next to Leave app running in notification area when the window is closed.

 

On Linux, you'll see badge notifications in your notifications area when the Slack app is running.

Note: Badges, like this one 1, appear in your channel list whenever someone @mentions you or notifies a channel you’re in.


Channel-specific and group DM notifications

You can set your notification preferences for specific channels and group direct messages. Choose the messages you’d like to be notified about, or mute conversations to reduce noise.

  1. Open the channel or group DM.
  2. Click the   details icon in the top right.
  3. Click   More, then click Change notifications
  4. Choose your notification preference, and whether you'd like to use different settings for your mobile device.
  5. Click the  close icon in the top right to save and exit.

Note: If you choose to be notified only about @mentions, the box next to Also include @channel and @here will be checked by default. You can uncheck this box if channel posting permissions or messaging permissions have not been restricted for your workspace.
